The Avcerage IQ point drop one experiences after reading threads in The Vestibule.

IGN cube's fanboy-favorite editor Fran Mirabella III unleashed an unwanted horse-head into the beds of many Gamecube owners. This happened when he scored Nintendo's "killer-ap" for the 2003 holiday line up - Mario Kart:Double Dash - the long awaited sequel to Mario Kart 64... with a dissapointing and medicore score of 7.9. This action outrages the fourm members of IGN and it became the gamecube's version of "pwned"

The sheer definition of mediocrity, lameness, and generally being mundane or insignificant.

Its the worse insult you can give someone.
